Passing a JavaScript function as an argument

In the process of developing a JavaScript application, I am tasked with creating a handler that can accept a function as a parameter:

Here is an example function:

function myFunction()
{
   alert("hello world");
}

This is the handler implementation:

function handler(action)
{
   action();
}

When calling the handler like this:

handler(myFunction);

It seems to work correctly on certain browsers, but fails to work on others. What could be causing this inconsistency?

Answer №1

If you want to achieve this result, follow these steps:

const collection = {
  myFunc : function()
       {
           alert("hello universe");
       }
}

function executor(action)
{
   action();
}

executor(collection.myFunc);

This code snippet is compatible across all browsers.
